FOYIVYIMER FOR SPINNINGMACHINVES;

.Application fuera April i9,

Y The present invention relates to ormers for use with spinning machines producing heads forpressure vessels. 'Headstor pressure vessels are provided with flanges and it was customary to employ a small radius in turning the flanges so that spinning plants are equipped with a great number ot Vexpenf sive mushroom'heads or toriners of various sizes but ot' short radius or practically no greater radius than is required for turning the flanges. There'is a demand for,k pressure Avessel heads of the so-called basket or elliptical types which Yrequire yfor theirspinning 'formers of long radius. Y y

The principal objectV of the. present invention is to meet thatv demand for long radius vessel heads of various types without discarding the present equipment of mushroom heads or tormers of short radius, and

Y to provide for the useoof these short radius mushroom heads along withv elements which provide for making vessel heads ot long radius andwhich are much less expensive than would be wholly new formers oit long radius.. To this andother ends the invention generally stated may be said to comprise'formers for spinning pressure vessel'heads'of diEerentV styles or types including so-called long radius, basket or elliptical heads, includingV interchangeable mushroom heads of short radius, and rings adapted in different combinations to provide different working contours including those of long radius, said rings and heads having means tor4 causing them to rotate in unison and with the master head of a spinning machine.

The invention also comprises the improvej ments to be presently described and nally claimed.

The construction and mode of operation of the modification illustrated lin Fig'.V 8 are as above described except that the ring or body Y 10 is lightened'by the Yprovision oir' cavities ff and externally its conformation provides in association with the contour of lthe mushroom head 1 not only a long radius, as indiy Y v `cated at 11,but.a contour adapted to produce In the following description reference will a substantially elliptical type of pressure vesselhead 12, as will appear byl reference to rvthe dash anddot lines.
